Definitions

  • the present invention relates to a sensor arrangement with one or more sun sensors in a motor vehicle, wherein the sensor arrangement is used in the region of the outside surface of the motor vehicle.
  • the solar radiation sensor system consists of a sensor subdivided into four quadrants that has a separate sensor element in each quadrant for detecting the incident solar radiation in the associated solid angle range.
  • the sensor here is located in the roof area.
  • such an arrangement has the disadvantage that the vehicle roof must be provided with a hole, which on the one hand can make it easy for the sensor to be damaged, and on the other hand results in increased expense for sealing the opening.
  • an arrangement of the sensor in the roof area is not always desirable for design reasons.
  • the sensor system should be capable of measuring and analyzing the intensity of incident solar radiation on the motor vehicle as a function of the orientation of the vehicle without producing overlaps in the solid angle ranges sensed by the sensors.
  • At least one sun sensor is mounted in the area of at least one exterior mirror.
  • the sun sensor or sun sensors is or are preferably placed in the area of the outer surface of the exterior mirror. Due to the position of the exterior mirror relative to the vehicle body, a sun sensor placed there can cover at least one half of the hemisphere above a vehicle side.
  • hemisphere refers to the hemisphere above the motor vehicle from which direct solar radiation is typically incident.
  • a sun sensor is advantageously mounted in the area of each of two exterior mirrors on opposite sides of the motor vehicle, wherein the sensor arrangement is preferably located in the upper part of the exterior mirror facing toward the hemisphere.
  • the sun sensors are designed with two zones (dual zone sensors). If the inventive sensor arrangement includes one sun sensor, this makes it possible to subdivide the hemisphere into two quadrants. If dual zone sensors are used on two opposite sides of the motor vehicle, it is possible according to the invention to subdivide the hemisphere under observation into four quadrants. This subdivision into four regions or quadrants corresponds to the division in high-quality air conditioning systems that allow individual climate control of four areas in the passenger compartment of the motor vehicle: driver, front passenger, left and right back seats.
  • each of the sun sensors prefferably be inset in transparent areas of the housing of the exterior mirror. This allows the sun sensors to be positioned with no adverse effect on the design possibilities for the motor vehicle.
  • Usable transparent areas include those provided for existing components such as directional signals, for example.
  • Further installation locations for the sensor arrangement within the exterior mirror include, for example, the top of the exterior mirror facing away from the road, or a side facing away from the motor vehicle.
  • a sun sensor with which the spatial area under observation is divided into two separately evaluated zones is referred to as a dual zone sensor.
  • Such a sensor normally has two individual sensors, which include photodiodes, for example.
  • FIGURE illustrates a top view of a motor vehicle with a fundamental inventive sensor arrangement.
  • FIG. 1 shows a motor vehicle 1 with a sensor arrangement 2 in the exterior mirror 4 and a sensor arrangement 3 in the exterior mirror 5 .
  • the sensor arrangements 2 and 3 are dual zone sun sensors, each of which is used to effect a subdivision of the hemisphere of the coverable spatial region 6 , 7 , 8 , 9 into two separate zones 6 and 7 or 8 and 9 . As a result, it is possible to measure in the direction of the forward 12 and rear 13 vehicle areas on each side 10 , 11 of the motor vehicle.
  • the hemisphere under observation is subdivided into four quadrants 6 , 7 , 8 , 9 .
  • the sensor arrangement 3 in the exterior mirror 5 covers the quadrants 6 and 7
  • the sensor arrangement 2 in the left exterior mirror 4 covers the quadrants 8 and 9 . This corresponds in an optimal way to the division of the passenger compartment of the motor vehicle into the areas driver seat 14 , front passenger seat 15 , and left 16 and right 17 back seats.
  • the sensor arrangement 2 , 3 working in conjunction with a control system of an air conditioner located in the motor vehicle, is thus capable of separately air-conditioning the individual passenger compartment areas 14 , 15 , 16 and 17 of the motor vehicle.
  • an air conditioning system that divides the passenger compartment into two areas, namely the driver side 14 , 16 and passenger side 15 , 17 can be regulated very easily.
  • the air conditioning system could cool the driver side 14 , 16 more strongly than the passenger side 15 , 17 , which is not exposed to direct sunlight.
  • the invention is not limited to the design shown in the example embodiment.
  • the number of sun sensors 2 , 3 , and also their position in the exterior mirror 3 , 4 of the motor vehicle 1 can vary.
  • a printed circuit board with electronic elements or receptacles with electrical terminals and additional sensors into the sensor arrangement 2 , 3 having one or more sensors 2 , 3 .
  • a temperature sensor and/or to use an ambient light sensor in the sensor arrangement 2 , 3 .
